Greg.
Thanks Greg...I'm pretty happy with the result to date...a bit more exposure time is always good, hence I can't be sure I won't add to the data set a tad more

off topic:
I just bought a house with a nice backyard & no trees -
& hope to set up an observatory dome within the next year.
I think that's the way to go.
I can't be bothered setting up my scope just for one night when usually the clouds
come rolling over anyway.
It's imagers with domes like you that seem to get the best & most data.

cheers

I purchased my Sirius Dome around 25 years ago.

I wish I had done it a decade earlier.

A dome will give you immediate sky access without the hassle or wear and tear on
what can be expensive kit by having to move/unpack/assemble/disassemble/etc.

You can nail the mount's polar alignment then forget about it.

They protect your telescope(s) from wind buffeting and stray light (e.g. my neighbours mini-sun floodlight)

While not inexpensive (a fully robotic 2.3m is currently around $16k).if I now divide the cost of my fancy hobby-shed by 25, the cost per year is peanuts.
.....in my case about $280 a year (well, I did buy it 25 years ago!)

Yes...I highly recommend getting one


As for deep-sky imaging from the "burbs", once again this is proof positive it can be done. If you run narrow band, you could set-up in Pitt street with a full moon, and no-one would be the wiser.

I gave a talk at Sydney Observatory on this very subject last year. It's all about maximising signal while reducing the noise.

Sure, I'd like to run my scope with excellent seeing in the high Chilean desert...but swapping out a filter set would be a a bit of a bugger
